a lot of people think that since a 30-30 does'nt shoot a bullet at blazing speed that it won't do the job. Take a look at the foot pounds of energy and you'll see that it's better than a lot of other calibers if you shoot at the ranges it was intened for. the core loct remingtons are fine as they shoot a heavier bullet than the hornady rounds that being said the lever revolution ammo is good stuff too. in short if he keeps the range within reason and is a good shot he will be fine. my hunting partner is taking a .243 because thats all he has, it's the smallest legal caliber and a poor choice for elk, he has used it before with mixed results. I look at the 30-30 as superior to a .243 because of the heavier bullet, taking a spare gun is a good Idea anyway. good luck and good hunting!!!
